The InvisiHead has proved to be more cost effective. It is a well engineered proactive intake system which actively addresses operation and environmental requirements compared to the highly reactive wedge-wire screen intake head systems. The overall performance of the Elmosa Seawater Intake System is higher than any other system operating in the water intake industry. The system entirely utilizes the natural process in its entire operation from the start to the end – from the point where the first water molecule at the offshore end of the system is gently drawn to the InvisiHead and smoothly guided through all the way to the pump intake at the onshore NatSep intake basin. 

In contrast, the wedge-wire screen intake head employs several reactive layers of measures needed to keep the system in operation. Wedge-wire screens are not a dedicated seawater intake head system like the InvisiHead but modified well screens. They have to be supported by a costly clean up system to convert them into operational seawater intake heads.
